| Abstract: | A new method based on the rough set theory and the fuzzy C-means algorithm is proposed to analyze the sensitivity of the influencing factors for slope stability. According to this method, the problem of the sensitivity analysis of the influencing factors for slope stability is translated into the problem of evaluating significance of attributes among the rough set theory. The fuzzy algorithm is then introduced to discretize continuous attributes; and the assessment model is set up to achieve the sensitivity analysis. Taking the circular slip slope for example, the sensitivity analysis of the influencing single factor and multiple factors for slope stability is performed; and it is shown that the proposed method is feasible and effective. |
| Keywords: | slope stability sensitivity analysis rough set attribute significance fuzzy C-means algorithm |
